JM Formaldehyde-free thermal and acoustical insulation is made of long, resilient glass fibers bonded with our bio-based binder. A wide range of thermal resistance R-values is available to provide thermal control for both vertical and horizontal applications. JM insulation is available unfaced or with a variety of facings, including kraft or foil vapor retarder.

Features

• Formaldehyde-free: will not off-gas formaldehyde in the indoor environment.
• Thermally Efficient: provides effective resistance to heat transfer with R-values up to R-49 (RSI-8.6).
• Sound Control: reduces transmission of sound through exterior and interior walls and floor or ceiling assemblies.
• Fire Resistant and Noncombustible: see Physical Properties.
• Durable Inorganic Glass: will not rot, mildew or deteriorate and is noncorrosive to pipes, wiring and metal studs.
• Superior Performance: bonded glass fibers are dimensionally stable and will not slump within the wall cavity, settle or break down during normal applications.

Physical Properties

• Flame Spread: <75
• Smoke Developed: <150
• Vapor Retarder (PERMS): 0.05
• Water Vapor Sorption: N/A
